I am sure I asked several times over 10 yrs for this - I need to be able to execute clean up code when the custom study is being removed from a chart. I need close named pipe and stop threads I created. It can be easily done with a call to some SC internal function like RegisterCleanupCallback(*func); It's 30 min work for you. Cmon |

There is a variable that you can check to see if the study is being removed. Refer to the following: ACSIL Interface Members - Variables and Arrays: sc.LastCallToFunction There simply should be no need for anything further. We use this variable in Sierra Chart studies, and it should be all you need. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

I wanted to do the same thing when my study is removed, but using the documented function doesn't work for me: if (sc.LastCallToFunction) { // This study is being removed from the chart or the chart is being closed // Insert cleanup code here if(sc.LoadChartDataByDateRange == 1) sc.LoadChartDataByDateRange = 0; MessageLogString.Format("Study removed"); sc.AddMessageToLog(MessageLogString, 0); } When the study is removed, if the chart is set to Use Date Range, I want to change it to Use # of days. Seems like this should be quite simple but, it doesn't do anything. No change in settings, and no MessageLog output. What am I missing? Thanks. Date Time Of Last Edit: 2023-10-17 16:18:25

Found the error, I wasn't giving this code block its own return; and was expecting to rely on one further down the code, which wasn't working. Inserted return; at the end here and now it works great.
